Question to the HM Treasury:

To ask the Chancellor of the Exchequer, if he will publish any statistical data his Department holds on the effective rate of inflation for households for different household make-ups, including those with multiple children.

The independent Office for National Statistics (ONS) is responsible for the calculation and publication of inflation statistics. In January 2022, the ONS resumed its publishing of CPI-consistent inflation estimates for UK by household groups, including by income decile and by retired and non-retired household. The ONS does not produce inflation statistics for households by number of children.^[1]

The Government understands that millions of households across the UK are struggling to make their incomes stretch to cover the rising cost of living. The government is providing over £15bn of additional support in the May Cost of Living Support, targeted particularly on those with the greatest need. This support package builds on the over £22bn announced previously, with government support for the cost of living now totaling over £37bn this year.
